ASCII configuration
file generator
This feature works by reading the
current configuration on the switch and
generating the appropriate NNCLI
commands to recreate that configura-
tion. It provides the ability to view and
store the switch configuration in a text,
editable format. The generated file can
be stored on an external server and also
used to restore the switch configuration.
Port naming alias
This feature gives the ability to name, or
specify a text string for, each port to
enable easy identification of the
connected users.
LED indicators
The LED indicators on the front panel
make it easy to monitor the switch and
port status and help in isolating and
diagnosing switch problems.
Network management
Enterprise Switch Manager
Enterprise Switch Manager* (ESM) is a
Java-based, real-time, configuration
management application for Nortel
Ethernet products including Ethernet
Switch 325 switches. It enables network
managers to discover, view and configure
more than 500 network devices and
their physical links on a topology map.
Configuration is stored in NVRAM
(Non-Volatile Random Access Memory).
Fault management
and resolution
With Enterprise Network Management
System (ENMS), the network manager
has quick access to the information
required to manage and isolate all
network events on Ethernet Switch 325
switches. Tools such as Physical
Topology View inform the network
manager of how a particular event is
affecting the physical connectivity
within the network. The ‘End Node
Locate’ tool provides the ability to locate
a failing end node and, with one mouse
click, provides access to the RMON
statistics for the failing Ethernet port
supporting that end node. These solu-
tions provide visual and statistical tools
necessary to quickly resolve network
events or to manage performance in
real-time. The Ethernet Switch 325
switches support “syslog” capability that
helps in troubleshooting network issues.
802.1ab auto-topology
Nortel’s Ethernet Switch 325 family
supports the 802.1ab auto-topology
standard in addition to Nortel auto-
topology. 802.1ab provides a method
for the switch and other devices that
support 802.1ab within the LAN, to
advertise their identification, configura-
tion and capabilities to neighboring
devices. Each 802.1ab supporting device
saves the information they learn inter-
nally, which allows the network manage-
ment system to model the topology of
the network by interrogating each device.
Simple Network Time Protocol
Simple Network Time Protocol (SNTP)
allows you to configure the switch to
synchronize Universal Coordinated
Time (UCT) to an accuracy of one
second. This feature adheres to the
IEEE RFC 2030 (MIB is the s5agent).
With this feature, the system can obtain
the time from any RFC 2030-compliant
NTP/SNTP server. Additionally, the
Ethernet Switch supports the capability
to modify the time zone reported by the
switch and automatically adjust the time
for daylight savings.
RMON
Network management begins with the
device. Ethernet Switch 325 switches
support four groups of Remote
Monitoring (RMON) on all ports and
are SNMPv1, v2 and v3 compliant. The
four groups of RMON are Alarms,
Events, History and Statistics. RMON2
support is achievable via port mirroring
and the use of an external probe. The
SNMP agent software resides in the
switch and uses the information it
collects to provide management for all
ports in the stack providing comprehen-
sive network monitoring capabilities.
SNMPv1 and v2 support
Full SNMP manageability is supported
across the Ethernet Switch 325 family.
Users can configure SNMP communi-
ties as well as establish access levels.
Traps are also supported with the addi-
tional ability to change the UDP port to
which traps are sent for security.
SNMPv3
SNMPv3 provides user authentication
and data encryption for higher security.
It also offers secure configuration and
monitoring.
